What is Cost-benefit analysis?

Cost-benefit analysis: Comparing a choice's benefits with its costs.

Where Cost-benefit analysis fits

Cost-benefit analysis is part of Strategy & Decisions in Management. Strategy is choosing where to compete and what to ignore. SWOT, KPIs and stakeholder maps guide decisions; opportunity cost says every yes is a no; sunk costs should not drive choices.
